I have bird hunted with both pumps, autos and when I was a boy I killed many doves with a single shot 410. I prefer the autoloader but many people swear by a pump action gun. Personally I feel more comfortable with the auto and feel like I can shoot it faster. It is what ever suits you. The gun type discussion is similar to which pick up tuck is better discussion, everyone is allowed to voice their opinion and each man thinks his is the best.
